[iOS] Real machine debugging report Unable to prepare xxx iPhone for development error

Introduction: Here is a record of a real machine debugging problem encountered during the development process:Unable to prepare xxx iPhone for development

report an error

When compiling and running the real machine, it will prompt the following at the end:

Unable to prepare xxx iPhone for development

Please check the connection to the device, and review all errors in the Devices and Simulators window.

By opening Window - Devices and Simulators, you can see:

Failed to prepare device for development.

if youare certain thax xcode supports development on this device, try disconnecting and  reconnecting the device.

problem solved

There are prompts to add compatible compatible files:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
复制代码

I just want to say that this is a must. If the Xcode version is not compatible with the mobile version, it will definitely not work. This is just a necessary condition.

Then, the old routine is still implemented. Once there is an abnormal real machine debugging problem, there are four steps:

• Command + Shift + KClear the Xcode cache, compile and run;
• 完全关闭退出 Xcode 重启, compile and run again;
• 手机重启, compile and run again;
• 电脑重启, compile and run again.

Basically, in the case of a sudden problem that was running well before, after these four steps, 90% of the problems can be solved.

I solved it here in the third step.

Summarize

Record it here for daily study.
