Update: The post is updated to make it compatible with Xcode 5 and iOS 7.
Update #2: You can now refer to this sample chapter of our Beginning iOS 9 Programming with Swift book to learn what you need to start iOS programming.
So far over 600 6000 readers have signed up the free iOS tutorials. First, thanks for those joining our community. Before we begin to talk about iOS programming, let's go through the tools you need to build your first app.
Powerful Combo: Xcode and SwiftUI. Xcode is upgraded once a year, around Sept-Oct, at the same time the new major version of iOS is released. Every update of Xcode brings improvements, new features, bug fixes, and access to the latest SDKs.
Yes, you need a Mac. It's the basic requirement for iOS development. To develop an iPhone (or iPad) app, you need to first get a Mac with Intel-based processor running on Mac OS X version 10.8 (or up). Probably you still own a PC, the cheapest option is to purchase the Mac Mini. The retail price of the entry model is US$599 (if you purchase via Amazon, the used model starts at US$490). You can pair it with the monitor of your PC. The basic model of Mac mini comes with 2.3GHz dual-core Intel Core i5 processor and 4GB memory. It should be well enough to run the iOS development tool smoothly. Of course, if you have more budget, get the higher model or iMac with better processing power.
Don't mix this up with the paid iOS Developer Program that we're going to talk about in later section. Everyone can register as an Apple developer for free. By registering the developer account, you're allowed to download Xcode, access documentation of the iOS SDK and other technical resources such as development videos.
You can go to Apple's developer website for registration. The registration process is very straightforward. Simply create an Apple ID (if you don't have) and fill in your personal profile.
To start developing iPhone and iPad apps, Xcode is the only tool you need to download. Xcode is an integrated development environment (IDE) provided by Apple. Xcode provides everything you need to kick start your app development. It already bundles the latest version of iOS SDK (short for Software Development Kit), a built-in source code editor, graphic user interface (UI) editor, debugging tools and many more. Most importantly, Xcode comes with an iPhone (or iPad) simulator so you can test your app even without the physical devices.
To download Xcode, launch Mac App Store on your Mac. If you're using the latest version of Mac OS, you should be able to open the Mac App Store from the icon in the dock. In case you can't find it, you may need to upgrade the Mac OS.
In the Mac App Store, simply search 'Xcode' and click 'Free' button to download it.
Once you complete the installation process, you'll find the Xcode folder in the Launchpad.
At the time of this writing, the latest version of Xcode is 5.1.1, which adds the support of iOS 7.1. For the upcoming tutorials, they'll be based on this version. Even you've installed Xcode before, I suggest you to upgrade to the latest version if you're planning to follow our tutorials.
A common question about developing iOS app is whether you need to enroll in the iOS Developer Program. The short answer is 'optional'. As mentioned earlier, Xcode already includes a built-in iPhone and iPad simulator. You can develop and test out your app right on your Mac.
Without joining the iOS Developer Program, however, the simulator is the only mean to run your apps. You can't deploy and test the app on your device. Needless to say, you're not permitted to submit your app to App Store. In other words, you can't sell your app!
The simulator is powerful, however, it doesn't simulate all features of iPhone. For instance, it doesn't come with the camera or video capture feature. So if you're building a camera app, the only way is to test it on a real iOS device. In other words, you have to join the iOS Developer Program!
So should you enroll in the program now? The iOS Developer Program costs US$99 per year. If you're a new comer and just start exploring iOS development, you can rely on the simulator to test out your app first. You can wait until you have a solid plan to distribute your apps on App Store before enrolling in the program.
That's all for today. Take some time to register your developer account and install Xcode. Once you're ready, check out the next post and start to build your first app.

Swift version: 5.2

By default the iOS Simulator shows whatever the time is on your Mac, but you can use Xcode's simctl command to override that with a custom time.
For example, Apple always uses 9:41am in their screenshots, because that was the time the original iPhone was announced. If you want to get the same thing in your simulator screenshots, use this command:
xcrun simctl status_bar 'iPhone 11 Pro Max' override --time '9:41'
You should replace the simulator name with whatever device you want to change.
Tip: The time shown is just a string, and can be whatever you want. You could use --time 'twostraws' for example, and that would work just fine.

Recording tool for pc. Apple could be in the process of developing a version of XCode to run on iPhones and iPads in iOS 14 and iPadOS 14, a leaker claims, a rumor that could lead to mobile apps being developed on the devices they will be ultimately used on in the future.
The iPhone and iPad are capable of a considerable number of tasks, with some people using the mobile devices as fully-fledged replacements for traditional computers and notebooks, like the MacBook Pro. One area that Apple hasn't covered so far is on-device development, which may change with the introduction of iOS 14 and iPadOS 14.
According to leaker Jon Prosser in a tweet posted on Monday, XCode is 'present on iOS/iPad OS 14.' Claiming he mentioned its existence during a live stream the week before, Prosser goes on to suggest the implications are 'huge,' as its inclusion 'opens the door for 'Pro' applications to come to iPad.'
I'm not gonna say that Final Cut is coming to iPad..
But XCode is present on iOS / iPad OS 14.
The implications there are HUGE.
Opens the door for 'Pro' applications to come to iPad.
I mentioned this last week on a live stream, but figured it was worth the tweet
As an example of what he alludes to, Prosser comments 'I'm not gonna say that Final Cut is coming to iPad,' referring to Final Cut Pro X.
Prosser's comment was elaborated upon by a reply from iOS developer Steve Moser, who points out 'the hidden Xcode Preview app is present in iOS 13,' though it is used as a companion app for the Mac-based version to show layout previews on a device's screen. However, in response to another message suggesting it could be the Preview app, Prosser hints it's not that by suggesting 'I know more than I've shown.'
So far, Apple has not allowed iPhone and iPad users to develop apps directly on the devices in an official capacity. The nearest it has allowed is Swift Playgrounds, an iPad app that teaches Swift development and experimentation, but stops short of app development itself.
It's not clear how a full version of XCode for iOS and iPadOS leads to 'Pro' applications on iPad. Given development for the platforms via a Mac already exists, it would be more prudent to consider the addition as making it easier for people to produce apps in the first place. Click recorder pc.
Currently a Mac or MacBook is required to develop an iOS or iPadOS app, though it is possible to test apps and visualize app layouts during development. By making it possible to develop on an iPhone or iPad, this can enable more people to get started creating apps as they don't need to acquire a Mac beforehand, reducing the barrier to entry for development.
Apple's plans for iOS 14 and iPadOS 14 won't be fully known until WWDC 2020, with Apple typically using the developer conference to unveil changes in its major operating systems.
