Recently, I was exposed to the issue of xcode jailbreak development. For jailbreak development, the iPhone device had to be jailbroken first, and then appsync was installed. After installation, the installation of IPA will no longer verify the validity of the program signature, non-Signed programs can also run directly on the device. You only need to ensure that the IPA is effective.
The IPA file itself is a zip file. Put the app folder compiled by xcode into the payload folder and rename it after compression.
To compile an appropriate app folder, you must select the SDK in xcode and change the code signature to non-signature.
In the compilation target, select iOS device. The app compiled for the simulator cannot run on the device, probably because the value in info. plist does not match the device.
1. Select don't code sign for code signing
2. Select iOS device for active Scheme
3. After compilation, you can find the path of the compiled app in the products attribute.
