Springboard Quit Unexpectedly for Empty Swift Project - ios

I created a new swift project, and changed nothing to the project. It is just an empty swift project. If I choose to run on iPhone 6, the springboard will crash. But if I choose others (like iPhone 5s or resizeable iPhone, even iPhone 6 Plus), the empty project works fine.
Does anyone know what's wrong with my xcode? And how should I deal with this problem?
The error message was so long that I cannot attach the whole message here. I'll choose some part that seems important to me.

App terminated due to cpu use in iOS 13.2

I have a location service based tracking and geofencing app which would run for days and weeks in the background on and iOS 12.2 ff device.
Now with iOS 13.2 the app gets terminated after a variable amount of time, but at least several hours, due to excessive cpu usage:

While in background the app does nothing more than to write each location update to a sqlite database and checking the current location against a safety perimeter.
There is no reason to assume that the app suddenly after several hours would require such a high cpu usage.
I have not the slightest idea how to approach the problem and I am not even sure if I can do anything about it or if it is a bug in 13.2 and I have to wait for a fix.
My first assumption was, that the old iOS 12.0 bug which terminated background apps without reason and which was fixed in 12.2 was back. But that here seems to be something new. I was able to run the test app iOS 12 terminates apps in the background for no reason for several days.
Any hint how to interprete the log and take action ?
Edit:
It seems, that this is related to iOS 13.2 message: nehelper sent invalid result code [1] for Wi-Fi information request
Location service queries the WiFi interface in second intervals. Instrument shows that these query calls have a memory leak.
Turning off WiFi on the device seems to solve the problem, though that is no true solution. Now waiting for iOS 13.3 to leave beta.
It turned out, that a third party framework that I am using launches calls to CNCopyNetworkInfo in second intervals. These calls could not fullfilled as my App had no WiFi capabilities enabled and thus the calls to CNCopyNetworkInfo caused small memory leaks that added up over time.
After enabling WiFi access capabilities the memory leaks vanished.

Swift iOS Project Leaks As Soon As An Empty Project Is Created

I've seen a fair bit of noise about "false positives," and have even encountered them, myself.
However, this takes the cake.
Easy to reproduce, using Swift 5/Xcode 10.2, create a new single-view iOS app.
Run Leaks.
You get these critters:
Malloc 64 Bytes 1 0x600001d084c0 64 Bytes Foundation +[NSString stringWithUTF8String:]
Malloc 16 Bytes 3 < multiple > 48 Bytes
Malloc 1.50 KiB 3 < multiple > 4.50 KiB
Malloc 32 Bytes 3 < multiple > 96 Bytes
Malloc 8.00 KiB 1 0x7fc56f000c00 8.00 KiB
Malloc 64 Bytes 10 < multiple > 640 Bytes
Malloc 80 Bytes 3 < multiple > 240 Bytes
Malloc 4.00 KiB 3 < multiple > 12.00 KiB
Using the simulator (XR, iOS 12.2).
That first one has a stack trace, but it's worthless.
Is there some way that I can correct for this noise? I'm writing an infrastructure component, and I need to:
A) Make damn sure it doesn't leak, and
B) Not have every Cocoapod jockey on Earth emailing me, and telling me that my component leaks.
If using a iOS 12.1 simulator , the leak instrument still can work (Swift 5/Xcode 10.2). Currently we are hoping it will be fixed in future versions.

How to dump memory pages of a process?

I want to dump the memory pages of a process once it finishes execution. I'm trying to use gdb for that, First I set break points at exit and _exit then I run the process inside gdb, once the process breaks I use info proc mappings to get the memory map of the process. it looks like the following:

Now I have two questions, first: getconf PAGESIZE on my machine returns 4096 which is equal to 0x1000, some of these memory spaces have different sizes though. how is that possible? are these spaces memory pages or just logical spaces? if these are not memory pages, how can I view the addresses of memory pages, or even directly dump memory pages to files?
my second question is the following: these addresses are supposed to be virtual addresses viewed by the program (not physical addresses), so why doesn't the program space start at 0? if I try to dump the memory starting from address 0 I get the following error: Cannot access memory at address 0x0. also why are there some regions in between these memory spaces that cannot be accessed (the region after the heap for example)? shouldn't the virtual space of a process be contiguous?
some of these memory spaces have different sizes though. how is that possible?
Easy: they span multiple pages (note that all of their sizes are multiples of 0x1000).
are these spaces memory pages or just logical spaces?
They are spans of one or more pages that have the same underlying mapping (the same file) and the same protections. I am not sure what exactly you call "logical spaces", but chances are you can call them that.
these addresses are supposed to be virtual addresses viewed by the program (not physical addresses),
Correct.
so why doesn't the program space start at 0?
Because long time ago VAX machines used to map something at address 0, and that made finding NULL pointer dereferences hard (they didn't crash). This was decided to be a bad idea, so later UNIX variants do not map zero page, and any attempt to dereference a NULL pointer causes SIGSEGV, helping you to debug your programs.

Xcode crashes when I try to create a outlet from a UIWebview to Header file

I am currently using Xcode 5 on my Macbook Pro which is running OSX Yosemite. I am trying to create an outlet from a UIWebview to a header file. When I let go of my mouse to create the connection, Xcode freezes and crashes. This is repeatedly happening no matter what I have done. I have tried restarting Xcode and my Macbook. Does anyone else have this problem or know how to fix it? Thanks!
I have added the logs from the crash(I couldn't include the backtrace because it exceeded the maximum characters in the body)

I think you should declare a IBOutlet in your header file. And then in Storyboard you try to connect the header file.
Have you ever tried to clean your product(Product->Clean)?
Then, open the xib file as source code and delete your IBOutlet info. Maybe XCode get confused about your IBOutlet.

iOS iPad panic crash log interpret

can anyone help me out in interpreting this panic crash log?
this happens during rotation with many images ... it involves javascript if that is of any help.

Thanks for any insight.
You should use instruments to check memory allocations and memory leaks. It could also be that the app was too long unresponsive and was killed, the text 4 waiters stuck for 12 secs could indicate that. The crash report content and format is pretty unique, haven't seen that one yet. So these are just guesses.
