LLDB不会在Swift中创建便利变量

Question

In an objective-c project, this command works well. but in Swift,

(lldb) expr unsigned int $foo = 5

error: :1:4: error: consecutive statements on a line must be separated by ';'

int $foo = 5

  ^ ; 

How can I fix this?

Answer 1

The expression parser uses the compiler's parser for the language of the current frame. Presumably you are stopped in a Swift frame, so you have to use correct Swift syntax. The swift equivalent is of your ObjC example is:

(lldb) expr var $foo : Int = 10

or since Swift does type inference, you can just say:

(lldb) expr var $foo = 10
