My classes in project randomly become invisible to other classes in intellij - intellij-idea

In my IntelliJ editor, I am facing this trouble that randomly some files becomes invisible to other files using them.
I have tried refreshing the workspace and even rebuilding the project but error won't go away even though the build never complains, the problem would suddenly disappear for a file and reappear for others.
When class is available it should not give red squiggly lines in the editor as it hampers in other code editing tasks.

I found the solution to this problem it's simple
goto File | then select invalidate cache and restart option, it resolved the issue, answering.

How can I force intellij to check all files?

When I'm using intellij sometimes I do very large refactors that the IDE can't help with. This often breaks a lot of files, but since I'm using either Typescript or Java it's relatively easy to find the problems.
My issue is that I can't seem to get Intellij to check those files unless I open them specifically.
The kind of checking I'm talking about isn't a specific inspection, it's just like the normal compilation problems.
So for example, I have a typescript project and I modified some stuff. When I open some of my React components intellij waits a second, and then highlights parts of it in red. I can go to those parts and see what the issue is.
I've tried forcing the inspector to run, and I've tried building the project, but neither one gives me the red squiggly love I need :^(
It feels like the project->build should force intellij to highlight all this stuff, but it seems to have no effect.

Codewarrior 10.5 broken links from problems window to errors in code

Typically when I compile a project I am working on in Codewarrior, the Problems window displays the errors and warnings it finds. From there, I am able to click on the errors and I will be linked to the location of the error in the code. In the current project I am working on, the errors are displayed in the problems window, but they do not link to the error. It shows the correct file and path, but the hyperlink to the location in the code is broken. In the console window, I can use the Next/Previous error buttons to navigate to error, but I can't do this from the Problems window - which I find easier to read. I know that this error is limited to this project, because I have opened other projects since this started happening and do not experience this problem in those projects. When I started this project, I copied an existing Codewarrior 10.5 project that does not have this issue and began changing names and editing. I have a suspicion that I might have missed something during this conversion process, but I am running out of places to look.
I'm not sure the exact reason for this error, but I did correct it by deleting the folders in the workspace folder and re-importing the project.

Intellij isn't analysing my code

I have a scala project that I'm working on in Intellij. When I opened it up this morning, suddenly none of the code is being analysed properly. The main things I've noticed are that it says every variable is unused (even when it's used in the next line), it doesn't show an error if I try to use a variable that doesn't exist, and I don't get any errors if I try to use a class I haven't imported. TODOs also don't come up in blue.
Does anyone know if there is some sort of setting that somehow could have changed that would affect this? The problem only happens in this one project, all of my other projects are fine.
Edit: I have tried closing it and opening it again, invalidating the cache and restarting and restarting the entire computer.
Edit 2: I forgot to say, if I try to run a test it will come up with the correct compilation errors for things that shouldn't work, but it still doesn't show the error in the code itself.
I'm still not sure why it happened, but I fixed it. I deleted the .idea folder and re-imported the project, and everything was analysed properly.

Xcode code folding issue

After updating Xcode(5.0.1),one of my project files is automatically unfolding the code every time i leave the file or close Xcode.And this weird behavior is bothering me a lot,i already tried to delete and recreate it but didn't worked.
Anyone knows what might be causing this single file to have its code unfolded?
With Xcode-9, this issue is resolved. Code folding is being remembered and saved by Xcode 9 Editor.
Code you have/had folded exact before last source build/save, is automatically stored upon document/file closure. And same will be visible as it was (folded) when you will open document/file next time.
You don't need to do anything (there is no any option in Xcode tool bar to enable or disable) to save your code fold.
There's no way around it. xCode will unfold your code automatically. Period. There is no option to "preserve" code folding. (sad, but true...)

How to see live list of syntax errors in WebStorm 7 (or IntelliJ)?

While editing a JavaScript file, the IDE shows highlights on the lines that have problems and displays the lightbulb when you're on one of those lines.
How can I see a live list of all problems found in the current file (e.g. syntax errors)?
The only way I found so far was to manually run inspection and check the inspection window. That's quite cumbersome. Even the "Problems" section of the Project window updates itself automatically as soon as I change the code (even without saving) - but it doesn't display the actual errors (only which files have errors).
Apparently the IDE knows what errors exist in the file - I just can't find a way to see all of them in a list.
In every other IDE I know, it is a built-in, enabled-by-default, feature: eclipse, visual studio, brackets, etc.
Apparently this is an open issue on the IntelliJ family of products. Please upvote that issue if you feel it is missing as well!
