For help with packaging your app for iOS, check out Kivy documentation - Create a package for iOS.
Package Your App for iOS
00:00 Instructions for building an application for iOS are a little more complex than Android. For the most up-to-date information, you should always use Kivy’s official packaging documentation.
00:14 You’ll need to run the command seen on-screen before you can package your application for iOS on your Mac.
The second command may not be needed, but there’s no harm in running it. If you’ve not used
pip to install
cython, as seen in the previous section to create an Android app, then you’ll need to do that too.
Once those are all installed successfully, you’ll need to install
To ensure you avoid hard-to-diagnose problems with Xcode, you’ll need to keep your
kivy-ios/ folder outside of the tree where your existing Python project is located. If you don’t do this, then Xcode will generate errors during the build process that can be hard to track down. So, on-screen, you’ll see the creation of a
kivy-ios/ folder, which is outside of the path of the folder where the development has been happening so far, as seen on-screen.
First, the new directory is created … and then navigated to … and then the
toolchain build is started, which can take some time. If you’ve installed but not run Xcode, then you’ll need to run it first, as this will install the extras, such as iPhone Simulator, that are needed for the iOS packaging to work.
02:26 If you run into SSL errors, then you probably don’t have Python’s OpenSSL set up. The command seen on-screen should fix that.
Once you’ve done that, try running the
toolchain command again. When you’ve run all the previous commands successfully, you can create your Xcode project using the
Your main application’s entry point must be named
main.py before you create the Xcode project. To ensure only the needed files are copied,
main.py will be copied into a new folder within the project, but it will be called
kivy-ios-source to make identification easier.
First, change back to the original
kivy/ project directory. Next, the source directory is created. And finally, the
calculator.py file is copied into it, renaming it in the process.
toolchain command is used to create the project. Note that
title will be the name of the project, and it can’t contain any spaces or illegal characters. Also, note that the
app_directory must be a fully qualified path.
04:03 On-screen, you can see the command that I ran, but your version will probably be different, as you’re using a different directory, so you’ll need to alter your command to suit.
First, navigate back to the
kivy-ios/ directory, and then use the
toolchain create command to create the Xcode project with the appropriate name and application source specified.
04:42 Now the project can be opened in Xcode using the project info that was output at the end of the project creation step.
04:58 The default settings will generate some warnings in Xcode, but regardless of these, you should be able to run the program by pressing the button at the top of the screen, as seen.
After a short delay, you should see the iPhone Simulator on-screen running your
kvcalc program. Note that if you want to submit your application to the App Store, then you’ll have to create a developer account at developer.apple.com and pay the yearly fee.
05:32 In the next section of the course, you’ll take a look back at what you’ve learned.
