如何删除或禁用xcode中的断点字段？

When I want to close or open a function in xcode I always accidentally add a breakpoint, that is very annoying so I wonder if there is a way to remove/disable it. I have searched for a solution but they are just people asking how to remove a breakpoint. I have checked through all the settings but not found anything. Or maybe there is an option to change how to add breakpoints like double click to add as in eclipse?When I want to close or open a function in xcod
