![]() click on an object to see its documentation in the right panel.mouse over your code and, if information is available, your cursor will turn into a question mark,.The best way to find documentation on iOS API is in Xcode: These indicate the file version control status, also used with git. You will notice single characters, such as ‘A’, ‘M’, ‘R’ showing up next to your source files. You can open any side panels by selecting them under Xcode’s View menu item. Bottom or Debug Area: console and debug output.Right or Inspectors: various inspectors.Middle/main or Editor: editor and storyboard.Left or Navigator: project and file explorer, warnings/errors, etc.DevCleaner comes in handy in cleaning up unused Xcode data. Over time, it will use up multiple GBs of your hard drive space. But it doesn’t clean up this data automatically. Xcode caches a lot of data to support different versions of the OS and to improve development speed. You may want to install Android Tool (yes, despite its name, it also works with iOS devices) for conveniently capturing device screenshots and screen recordings from your Mac. Xcode may be buggy: if it does unexpected things, restart and see if malbehavior persists. In which case, you’d have to download a beta release of the next version of Xcode. ![]() If you’re running a beta version of iOS, the version of Xcode on the App Store may not support your iOS yet. Open and install all other components it asks for.If you want to explore use of other IDE ( not recommended), see references below. You can use a different IDE (such as VSCode or AppCode) or do your development on a different platform, but in the end you’ll still need Xcode running on macOS to build an iOS app. your entire team should be on the same version of Xcode, macOS, and iOS.you will develop only in Swift, not Objective-C.Settings > General > About > Software Version. To check your iOS version, on your phone navigate to you have a device running iOS 16 or later.If you are contemplating cross-platform mobile development, please consult our collection of articles on industry experiences with cross-platform solutions. All course projects must be built natively. ![]() The course does not support cross-platform frameworks, including React Native and Flutter. We will use only Swift to develop iOS apps, not Objective-C. If you are exploring other options to develop for iOS without a Mac, please review, Have iPhone but no Mac?. ![]() In the Groundworks lab, the Macs under the signs Recording Booth and Conversion Rack do not have Xcode installed and cannot be used to complete the labs. If you have an iPhone but no Mac, you can try to get a loaner laptop from ITS, use the iMacs in the ITS Campus Computing sites and the Groundworks at MediaLabs to develop your labs. So aside from requiring Xcode running on a mac, we also require that you have access to a physical iPhone to complete the last three of the five iOS labs. Without physical access to a device, you can’t take photo/video, read the magnetometer, or perform biometric check (despite the simulator’s Touch/Face ID feature), which our labs have you do. The iOS simulator is powerful but, unfortunately, it doesn’t simulate the camera nor magnetometer and I’m not able to get simulated biometric to work on the simulator. You will need Xcode 15, which would require macOS Ventura 13.4 for your development host, which would mean your Mac cannot be too old (2017 for iMac and MacBook or 2018 for MacBook Air and Mac mini). This means your iPhone must be at least iPhone SE (2nd gen), Xr or later (use your browser search and search for “compatible”). Apple requires the use of Xcode running on macOS to develop for iOS.
