How can I understand an iOS app written with Objective-C or Swift?

It's weird question but If I have an .ipa of an iOS app. How can I understand an iOS app written with Objective-C or Swift? Using decompiler or another way?

Solution

  • You'll need an app to decompress zipped files like this one.

    It's easy:

    1. Right click on the IPA file
    2. Open With > The Unarchiver
    3. Now you have a folder with the same name of the IPA file. Open it.
    4. If you see a folder named SwiftSupport then there's is some Swift code into that IPA.
