As an award-winning **[iOS app development company](https://www.digitalbrain.co.in/best-iphone-ios-app-development-company/)**, one of the most common questions we get asked is “How much does it cost to develop an iOS app?”

The **[cost to develop an iOS app](https://www.digitalbrain.co.in/how-much-does-it-cost-to-develop-an-ios-app/)** can vary greatly based on the app's features, complexity, design needs, and development timeline. But on average, app development costs for iOS apps range from:

- $10,000 to $50,000 for a simpler database or utility app
- $50,000 to $100,000 for an average app with common features
- $100,000 to $250,000+ for a more complex app with advanced functionality

**Factors That Influence iOS App Development Cost**

There are several key factors that determine how much it will cost to create your iOS app:

Features and Functionality - The more features and screens your app has, the more development time is required. Complex apps cost more.
Custom Design - Apps with unique branding, animations and UX typically cost more than using an existing template.
Developer Rates - Developer hourly rates range from $50 to $150+ based on experience level.
Testing Requirements - Extensive testing across devices and iOS versions adds development and QA time.
Backend Work - Integrating APIs, databases, and complex back-end systems increases costs.
Maintenance and Updates - Ongoing app maintenance, new iOS version support, and feature additions increase long-term costs.

##### IF-THEN-ELSIF-ELSE

IF boolean-expression THEN

statements

\[ ELSIF boolean-expression THEN

statements

\[ ELSIF boolean-expression THEN

statements ] ...]

\[ ELSE

statements ]

END IF;

IF-THEN-ELSIF-ELSE is used to execute the corresponding statement by detecting multiple conditions in the IF statement. In general, it is equivalent to the nested use of the IF-THEN-ELSE-IF-THEN command, with the difference that only one END IF statement is required.

The following example uses the IF-THEN-ELSIF-ELSE statement to calculate the number of employees in the $25,000 compensation range.

```
\set PLSQL_MODE on
CREATE OR REPLACE PROCEDURE emp_test_4()
IS
	v_empno emp.empno%TYPE;
	v_comp NUMBER(8,2);
	v_lt_25K SMALLINT := 0;
	v_25K_50K SMALLINT := 0;
	v_50K_75K SMALLINT := 0;
	v_75K_100K SMALLINT := 0;
	v_ge_100K SMALLINT := 0;
	CURSOR emp_cursor IS SELECT empno, (sal + NVL(comm,0)) * 24 FROM emp order by 1;
BEGIN
	OPEN emp_cursor;
	LOOP
		FETCH emp_cursor INTO v_empno, v_comp;
		EXIT WHEN emp_cursor%NOTFOUND;
		IF v_comp < 25000 THEN
			v_lt_25K := v_lt_25K + 1;
		ELSIF v_comp < 50000 THEN
			v_25K_50K := v_25K_50K + 1;
		ELSIF v_comp < 75000 THEN
			v_50K_75K := v_50K_75K + 1;
		ELSIF v_comp < 100000 THEN
			v_75K_100K := v_75K_100K + 1;
		ELSE
			v_ge_100K := v_ge_100K + 1;
		END IF;
	END LOOP;
	CLOSE emp_cursor;
	DBMS_OUTPUT.PUT_LINE('Number of employees by yearly compensation');
	DBMS_OUTPUT.PUT_LINE('Less than 25,000 : ' || v_lt_25K);
	DBMS_OUTPUT.PUT_LINE('25,000 - 49,9999 : ' || v_25K_50K);
	DBMS_OUTPUT.PUT_LINE('50,000 - 74,9999 : ' || v_50K_75K);
	DBMS_OUTPUT.PUT_LINE('75,000 - 99,9999 : ' || v_75K_100K);
	DBMS_OUTPUT.PUT_LINE('100,000 and over : ' || v_ge_100K);
END;

/
\set PLSQL_MODE off
```

Deprecated dispatchables removed from Polkadot SDK
Tags: web3, rust, substrate, blockchain
Published: 2023-09-28 10:44:21

## What’s happening?

In December last year, [a PR was opened to](https://github.com/paritytech/substrate/pull/12951) to deprecate Currency and introduce holds and freezing into fungible traits. As part of this PR, `Balances::set_balance` was replaced by [`Balances::force_set_balance`](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/pallet/struct.Pallet.html#method.force_set_balance) and `Balances::transfer` was replaced with [`Balances::transfer_allow_death`](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/pallet/struct.Pallet.html#method.transfer_allow_death).

As much of the ecosystem uses `transfer`, a compatibility stub was added to give ecosystem teams time to move to these replacements. This time has elapsed and [the stub has been removed in this PR](https://github.com/paritytech/polkadot-sdk/pull/1226).

## Why was this change made?

Some improvements were made along with the deprecation of the Currency trait. The hope is that these changes make the dispatchable's names better reflect their functions.

For example, when calling `transfer`, it was not immediately apparent that it could end up with an account being reaped. However, `transfer_allow_death` is more explicit about the potential repercussions of using this dispatchable over an alternative such as `transfer_keep_alive`.

## Code changes

You should use the fungible trait API for Balances rather than calling these dispatchables directly, as the long-term plan is to remove the dispatchables and have all pallet access be via [XCM](https://docs.substrate.io/learn/xcm-communication/).

However, if you need to refactor your code to use the replacements, note the following:

- `Balances::set_balance` becomes [`Balances::force_set_balance`](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/pallet/struct.Pallet.html#method.force_set_balance) and only accepts the free balance _(not the reserved balance since this no longer makes sense)_.
- `Balances::transfer` becomes [`Balances::transfer_allow_death`](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/pallet/struct.Pallet.html#method.transfer_allow_death) or [`Balances::transfer_keep_alive`](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/pallet/struct.Pallet.html#method.transfer_keep_alive)

# Use a ratio of 100:42 for best results.

I'm very interested in art experimentation as well as tech and sustainability. I recently participated in a live programming workshop meant for music creation. One of the guys conducting the workshop mentioned the fact of slight imperfections (usually not noticeable by the human regular ear) of human artists against programmed music. Somehow this made me think of how some imperfections lead to more interesting works than the one that was previously attempted. How could I work around a terminal toy that was "imperfect" in its attempts to play music?

I'm very interested in sustainability and de-escalating tech resources, so I refused to work towards AI, but I thought of working with GA. The idea is for the toy to attempt to reach a collection of notes, each attempt more close, but not quite until it reaches the correct ones.

In order to do [this](https://git.sr.ht/~alienagain/TinEar) I chose python3 and a very simple GA structure, the same that would try to guess a word. 

This is an example usage:

```
python3 tinear.py
TARGET: AABC
MAXIMUN GENERATIONS ALLOWED: 7

Generation: 1	String: AACC	Fitness: 1
Generation: 2	String: AABC	Fitness: 0
```

In this case it was lucky and guessed the right one the second time (generation 2). In order to play music directly from the terminal, I use `os.system` defining a command with variable chords (the ones asked to the user at the execution) and `play -n synth pl`.

The result is that each guess, the terminal plays the attempting tune, making it fun when doing some live coding jams.

I mixed the tinear attempts with some synthesizer tunes using teenage engineering devices and created some imperfect, yet fun music! You can find the script [here](https://git.sr.ht/~alienagain/TinEar/tree/master/item/src/tinear.py).

Fast-Tracking Electric Vehicle Adoption in India
Tags: javascript, webdev, react, discuss
Published: 2023-09-28 10:22:01

India is at a stage in its path for sustainable growth where decisions must be made. As one of the largest and fastest-growing economies in the world, the nation must strike a balance between economic development and environmental stewardship.

As EV usage has increased globally, India has set lofty goals for EV penetration in order to meet this challenge. However, with only 1.32% of India’s registered vehicles being electric vehicles in FY 2021–22, reaching the stated goal of 30% EVs by 2030 will require cooperation from all parties, including the public, commercial sector, and consumers.
