Do not modify the Xcode project load reveal

With regard to the iOS UI debugging tool reveal configuration, many beginner friends may search the Internet for some articles, most of which are about how to configure the Xcode project, by adding some library files, and in the program to write additional code to invoke the reveal service, This ensures that the project can be attached to the reveal for analysis when the program is debugged.

This is cumbersome, and every project needs to repeat these tedious steps, which is unbearable. To this end, in the next through a number of analysis attempts, finally found a way to once and for all. Let's introduce this method to you now. This method was not invented by me, this is the method provided by reveal official documentation. But there is little mention on the internet, I am here to introduce this method to you. This method invokes the reveal service through the Xcode Breakpoint command, and then guarantees that the reveal can be attached at any time when the program is running in the emulator, which makes it easy to analyze the hierarchy of the UI. This method only needs to be configured for Xcode once, since then, reveal can be used at any time, which is extremely convenient, avoids every tedious project configuration, and does not need to write any code. Here I will give you a detailed introduction to the specific configuration method.
