Xcode is the development environment that all iPhone apps are created in. Xcode is available for free from Apple, but requires OS X 10.8 or later to be installed. There is no official way to run Xcode on a Windows or Linux PC. This means that if you want to develop an iPhone app but don't have a Mac, you'll need to invest in one first. To develop iOS 8 apps, you will need Xcode 6.0.1 and the iOS 8 SDK, both of which are available from Apple. The iOS 8 SDK contains a significant number of new APIs that allow you to create all kinds of new app experiences, including iCloud integration and Touch ID. To develop iOS 10 apps, you'll need Xcode 8 and the iOS 10 SDK, also available from Apple. There are significant changes to the Swift language and the SDK in this version of Xcode that you'll want to be aware of, but the good news is that there are to be no more "code breaking" changes to the Swift language after this version. While you can code completely within Xcode, you'll find that working with large chunks of code is much easier if you have a dedicated text editor that specializes in programming syntax. TextMate and JEdit are two very popular choices. If you plan on creating custom art and designs for your app, you will want a program that can create vector graphics. Vector graphics scale without losing clarity, and are essential for a good-looking app. Popular vector programs include CorelDraw, Adobe Illustrator and Xara Designer, which are commercial, and Inkscape, which is free. A nice, free, vector graphics drawing program is DrawBerry. It is not as powerful as the professional programs, but it is good for a first-time user, or if you just don't want to pay for something just for one use. Objective-C is the programming language used to create functionality within iPhone apps. It handles data and object manipulation. Objective-C is a derivative of the C family of languages, and is an object-oriented language. If you already have a basic understanding of C or Java, Objective-C should be, for the most part, pretty easy to grasp. A newer option is to create your app using the Swift language, the follow-on to Objective-C. Swift has a much friendlier syntax and a more modern feel. While it's possible to build a basic app without knowing Objective-C, you cannot perform any sort of advanced function without coding it yourself. Without Objective-C, all you can do is move back and forth between screens. There are a variety of tutorials available online, as well as a wealth of information to be found in various books about Objective-C or Swift. If iPhone app development is something you want to take seriously, you'll be well-served by having some resources handy. Some of the more popular online Objective-C and Swift communities include the Apple Developer Forums, the iPhoneSDK Google Group, and StackOverflow. If you simply don't have any interest in learning Objective-C or Swift or don't have an artistic bone in your body, there are a large number of freelancers and development teams out there that may be able to take on various aspects of your project for you. Outsourcing your development is a complicated process, but can save you lots of headaches if you're not the programming type. Make sure that everyone involved signs a Non-Disclosure Agreement, and that pay structures are in place before any work begins. Upwork (previously oDesk and Elance) is the most popular freelancing service on the Internet that has hundreds of developers and artists of all skill levels. In order to distribute your app on the App Store or give it to others to test, you will need to sign up for an Apple Developer account. The account costs $99 per year and will require you to enter in tax and bank account information. You can create your account at the iOS Dev Center website. Once you've signed up for a Developer account, you will have access to Apple's development resources. These resources include a variety of sample projects which can give you a tremendous amount of insight into how app development works. Find an example that is related to the kind of app you want to create and mess around with it in Xcode.

If you don't already know how to read music, it can take a lot of time to memorize and proficiently read sheet music. Tabs are an easier and more intuitive way to write music for beginners that doesn't require any formal education. Tabs will simply tell you where to put your fingers on a fret board and how to generally play a song. While traditional sheet music can tell you the duration of the notes in a song, tabs require you to listen to the music itself. If you're interested in playing other instruments, you should learn how to read music. Listen to acoustic guitar songs that you enjoy and choose one that you'd like to learn. When finding your first song, try to find a song that has an easy chord progression. Listen to the song and determine how many chord changes it has and the speed in which the song is played. If there aren't that many chords or the song seems simple to play, you should choose that song as your first song to learn. Easy songs to learn include "Three Little Birds" by Bob Marley, "Hey There Delilah" by the Plain White T's, and "Upside Down" by Jack Johnson. Type in the name and artist of the song and look up the tabs in a search engine. Once you find the tabs, you'll be able to see which chords and notes that the artist is using to play the song.

One-sentence summary -- Use tabs instead of sheet music. Determine the guitar riff that you want to learn. Look up the tabs for the song online.

Be sure to include everything. If you think it was wrong it wouldn't hurt to perform a second evaluation. Be sure to include all lies, disaffection and failures. The idea is to expose all of your wounds. Part of the healing process is to realize what you did wrong and that is where the list we made earlier comes into play. This step varies in difficulty depending on the problems each individual has. There are no short cuts. You must allow time to heal your wounds, but have the self-confidence to keep working on recovery even if it seems distant. Time will heal all wounds, but only if you keep working on your recovery.

One-sentence summary -- Write down a list off all your errors. Apologize to yourself and others around you that your behavior/ action has affected. Actively think about what you did wrong and correct the smallest mistakes first. Be patient.

To get the ultimate look from your at-home gel nails, start with the ultimate blank nail. Take the time to cut, file, and shape your nails. Before you cut them, decide what shape you want. Cut the basic shape and then file the tips. Finally, finish shaping by rounding the surface of your nails with a buffer. You can create round, square, pointy, almond, or oval nails. Because gel nails are based off of your nails, this is when you shape your nails. It is not like applying acrylic nails that can be shaped during/after application.
