Xcode slow build time in editor - ios

When I'm editing a single file in Xcode, it takes several seconds to any kind of syntax error to show up. Sometimes errors don't even show up until I go to the menu and build manually. It makes development awfully slow as I have to constantly wait to check if I miswrote something...
I don't think it's because of the machine, though its a Macbook Air, but I do Android development on this machine too, and Android Studio can show me syntax errors just fine.
Is there any way to make this part faster? Or I need a better machine?

FMX debugging Can't bind address, Address already in use

First time debugging from PC to Mobile Phone work fine, when try again get error.
Any solution how fix this when try more debugging.
Add -debugport=54321 to Run->Parameters Parameters. By the way, the "inconsistent certificates" message is because the apk on the device was compiled with a different version of Delphi than the one you are using right now. You will have to uninstall it from the phone first. You can also use -cleaninstall in the Run->Parameters Parameters field.
There is no easy and fast solution.
You may need to:
Restart IDE
Kill adb.exe
Restart Windows
Restart device
Sometimes you will be able to debug again after doing only some of the above steps, however often you will need to do all of them.
Since every try takes plenty of time, I found out that complete Windows restart + device restart is the fastest thing to do.
With Delphi 10.3.3, it is enough to restart the device. After restarting the device problem goes away. It seems after the cancelation of code execution of the project debugged, the debugging service on Android continues to run. At this point, when new debugging started, IDE tries to run a new service with the same id of previous running service.

Xcode builds are taking much longer than usual and causing MacBook fans to go crazy

I am building/running a relatively simple chat application. Every time I run/build the application, the fans on my MacBook get extremely loud and my computer begins to heat up very quickly. Furthermore the builds are taking a ridiculous amount of time to finish, even after editing just a single line of code.
I opened up activity monitor and noticed that "SourceKitService" was using 100% of the CPU.
Earlier today, I deleted the DerivedData folder for my project, and that still doesn't seem to solve this issue.
How can I fix this?
Try doing a deep clean (Command+Shift+K), deleting derived data, closing Xcode, and restart Mac. That usually helps me. However, when I'm running apps on my 8GB memory Mac some cause the same issue while my 16GB Mac runs them just fine.

devenv.exe hogs CPU when debugging

Short version:
When I debug ASP.NET MVC apps in VS2013 and try to edit razor views or css files, the CPU usage of devenv.exe skyrockets to the point where VS becomes unresponsive. Browser link is turned off, yet this still happens. Restarting debugging doesn't help, restarting VS doesn't help, restarting windows helps only for a short while, before the problem shows up again. How do I fix this?
Long version:
I'm having some trouble with Visual Studio 2013. Namely, after I start debugging an ASP.NET MVC app devenv.exe starts hogging CPU (to the point where Visual Studio becomes unresponsive). Some time ago this was happening only from time to time, but now it happens nearly always.
At first I thought that it was a problem with Browser Link, but the problem didn't go away after I turned it off and closing the browser while debugging doesn't have any effect.
Stopping debugging makes it stop hogging CPU, but it doesn't make the problem go away when I debug the app next time. Restarting VS doesn't help either and restarting Windows only helps for a little while.
The main clue here is that devenv.exe shows low CPU usage while VS window is not active. Switching to VS window makes devenv.exe use more CPU, but trying to do anything in VS (especially editing a razor view or css file) makes the CPU usage skyrocket.
Anyone got an idea what could be causing this problem and how to solve it?
Being unable to edit css and views while debugging is seriously lowering my productivity (the app takes good minute or two to start).
P.S. The app I'm working on right now is a nopcommerce based shop, but I had this problem before while debugging MVC apps that had nothing to do with nopcommerce.
I didn't manage to find the source of the problem, but closing all editor windows in VS seems to make it go away. If there are further lag spikes, restarting debugging might be also a good idea.
Since I didn't see this problem in a new project, it might be related to the sheer size of the solution, the number of files being opened in the editor at one time (though the problem remained even when I left one view open), the time those files where opened in the VS (I'm not entirely sure why this would be a problem, maybe it has something to do with the file history).

How can I debug this error: 'Debugging information for iisexpress.exe cannot be found or does not match'?

I've been working on an MVC 5 code first project for a few months and (seemingly) out of nowhere, Visual Studio is refusing to debug and giving me some strange errors.
When I try to run the application Ctrl+F5 it builds ok but the browser never gets beyond the loading stage, I still have the pinwheel in the browser tab, but the app never loads.
When I try to debug the applicaiton F5 it builds ok, but then comes up with 2 errors, firstly Debugging information for iisexpress.exe cannot be found or does not match. Cannot find or open the PDB file. and then Process with an Id of xxxx is not running.
I've tried loading symbols from MS (https://stackoverflow.com/a/8138518/1778169), using a different database name, uninstalling VS extensions, performing all Windows Updates, repairing the VS installation and even reinstalling VS entirely. Nothing seems to help.
I'm not very familiar with PDB files, but I have done nothing knowingly to change this, and they seem to be in the right place:
I am running out of ideas, but really want to avoid a Windows reinstall if possible.
It's only happening in this one project, so the problem would seem to be with the project itself, not the installation. But I have no idea where to start debugging this problem, or looking for a solution.
Possibly Relevant
I tried running the app on a custom domain (set up in the hosts file and IIS Express's ApplicationHosts.config file). In an attempt to solve this problem I reverted these settings back to the default localhost:[port]. This doesn't seem to have made any difference, but thought I should mention it just in case.
My problem was that the Native Code box was ticked in the Debuggers section of the Web section in Project Properties.
I don't know how this came to be ticked, I certainly never ticked it.
Either way, unticking this box solved my problem.

application wont start or load in blackberry simulator

I'm developing an application on two different machines (home and work) and while the home one seems to run just fine, the work one is, for lack of a better word, possessed. It has been exhibiting the following issues:
When loading the application, it will start at the simulator's main screen instead of starting the application at random intervals. You can start the application and have it work fine, then close the simulator, reload, and have the same codebase not load.
Going to applications doesn't show the application itself, in fact it never does.
Trying to load the applications cod file (File->load java program) never works. Tried the steps in this thread, with unreliable results.
Extremely small changes, such as modifying the value of a width variable by one, commenting out a function such as makeMenu or adding a button will cause code to no longer work, with no errors shown by the IDE.
Using clear.bat with sometimes work, sometimes not. Same with manually removing all files with the name of the project.
reinstalling the eclipse environment and the blackberry plugin did nothing more then burn off an hour.
having "load on startup" in the blackberry_app_descriptor.xml file is set.
Both systems are using Eclipse 3.5.1, BB plugin for eclipse 1.1 beta, Java 4.5 with the 8300 simulator. THe only difference that I am seeing is the operating system between the two systems. The work one being XP Sp3, home being vista. THe vista one isn't perfect, but I can test variable changes without flipping a coin to see if the app will even load or not.
I've tried the solutions that were similar on this forum, such as this one, but it looked to be that those solutions are dated as none of the options for the steps existed in my eclipse install.
So has anyone ran into such baffling behavior, and can it be fixed? Anything that I might have missed that could be tried?
I've been seeing this behavior with the new 1.1 plugin, the application doesn't load on startup and the FIle->load java program doesn't help. For me, the solution was I have to run a clean build every time, that is the eclipse clean and build instead of just build, not the clean.bat... Hope this helps!
Try clearing resources that have improper naming structure in your projects stuff with spaces or special character in the name of the file.
It took me two days to figure out.
One solution i got regarding your problem.
As I See Please run the application first time as Run as blackberry simulator
that is got start and here pick up run and then Run as Blackberry simulator
