reply me plz
In XCode, you can run Build and Analyze. XCode shows memory leaks with arrows of you bad memory management.

Problem
I profiled my app and found that I have memory leaks. Unfortunately, I'm unsure how to diagnose it in this case.
Here is what the memory leaks show in Instruments:
Question
It says that the Responsible Libraries are system libraries, does this mean that this leak is a bug, or is it on my part?
Is my app somehow causing this leak?
If so, what could possibly cause it? I don't want to post all my app code making for an unreasonable question, so help for where I need to look would be a great help.
I have added tags for Swift and SwiftUI because it looks like the leak is coming from SwiftUI shown in Instruments.
There is a bug in SwiftUI which causes Memory Leak as of Xcode 11 Beta 3. You can also verify this by building a simple app which shows just “Hello World”, the instruments show a leak here also.
I just got the new xcode and the tool I used to test for leaks isn't there under run anymore? Can someone tell me how to test for leaks?
Instead of having direct instruments in the menu, you start the app using the "profile" option and it asks you which instrument you want to use - there are the instruments you used to see, including Object Alloc and Leaks. There's also a very useful Zombie tool to help with over-released objects.
i am running my program using iphone simulator n at some point application crashes..but there is no error...just getting Debugging terminated in debugger console
how i can check this what is the problem of crashes?
How about memory leaks?? If you are alloc-ing a lot of variables and not releasing them this can cause memory leaks. Which will in time cause the app to crash with a black screen. Try running your app with the "Leaks" tool. Go to Run -> Run with Performance Tools -> Leaks. Go through everything you can in the app with this tool running and it will inform you of any memory leaks.
Here is a good link for information about using the Leaks Instrument:

Also check your code!! If you know where its crashing go and check the code and make sure your doing everything you intend to!
Try to look into crash logs. You can find them in ~/Library/Logs/CrashReporter
Can any one guide me in clearing the memory leaks in the iphone code.
in xcode editor it does not shows any issues,
so i hav uploaded my app to the AppleStore.
they rejected my app.
so kindly help me what is my issue?
how to rectify it.
Thanks in advance
In Xcode, select Run -> Run with Performance Tool -> Leaks.
Use performance tool to help you find memory leaks.
First, Thanks to all for your quick help for any questions asked in this forum.
I just want to know what are the testing tools coming up with Xcode on Mac as i need to test my iPhone application professionally (or) What do you suggest to use debug and test my application using any (or) built-in tools?
Thanks.
The first thing I try is Xcode's "Build and Analyze" menu command.
Next thing is to run Instruments and look for memory and object allocations and disposal. Instruments should keep you busy for quite a while as it can provide you a wealth of information, including network performance and graphics utilization.
When using instruments, the first method you should check is memory allocation and leaks. When your application leaks, it will spike. Click on this leak and then extend the details to find the exact whereabouts of the leak.
However read the documentation on it all first.
