Looks like they're called "special characters" here: linkText. I thought there would be more of them.

I found the following here: Designing and Creating a CloudKit Database. Important During development, you can change your schema as much as you want, but once it’s deployed to production, you can’t delete any part of it. You can only make additive changes, such as adding a new field to a record type, or adding new record types. This still doesn't tell me if I can add or remove indices to record types after production. I would need less to remove indices than to add indices.

Again I find this: The Development and Production Environments After you deploy the schema to the production environment, you can still modify the schema in the development environment but can’t delete record types and fields that were previously deployed. This still doesn't specifically tell me exactly what I want to know.

Ok. I found the string instance property of the class. I would like to see documentation for that anyhow. Anyone know why it's not in Apple Developer Documentation?

Did you ever figure this out?

Apple documentation says that Operations run synchronously. Why then does the code continue to run after an operation is added to a queue? Here is my code: let op = BlockOperation(block: { print("Done") }) let qu = OperationQueue() qu.addOperation(op) print("after!") Here is the debug results: after! Done

What is the purpose of this guard statement?

I don't think it's possible to save a record in one database and another record in a different database at the same time, so the parent record and the child record I mention in my post would have be saved in different lines of code. I think. I don't think it is possible to save two records in two different databases using CKModifyRecordsOperation. I don't know if there is a way at all.

No. Do you have a source of information about that that you particularly like more than other sources?

Anyone figure out how to bypass the action sheet? Is that possible? @eskimo @ilovecats516

Did you ever work this problem out? What's the solution?

Yeah. That works. I'm hoping to be able to call attention to the message in a more obvious way to the person receiving the message. He could put the sender in the contact and set emergency override on.

Since the error says, 'The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.', where do I type "thread return -x"? The debug area doesn't let my type in it in Playground as it does in Xcode.

Does anyone have an answer to this question? Also, since the error says, 'The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.', where do I type "thread return -x"? The debug area doesn't let my type in it in Playground as it does in Xcode.

Has anything changed about this? I'm actually in Playground, not Playground in Xcode, and I am able to set breakpoints in a file in the Source folder, but code execution doesn't stop at the breakpoints. I know the code runs to those points, because there are print statements that print into the debug area that are placed between those breakpoints.
