Question 1

PMJSON vs JSONSerialization in Swift: which should I use?

Accepted Answer

PMJSON offers better error messages and type safety, but JSONSerialization is faster and built into Foundation. Use PMJSON if detailed error diagnostics are crucial; otherwise, JSONSerialization is more performant and integrated.

Question 2

How to parse a JSON array with PMJSON in Swift?

Accepted Answer

Use methods like json.mapArray('key', YourType.init(json:)) or iterate with getArray() accessors. For example, try json.getArray('items') to safely extract and process array elements with error handling.

Question 3

Does PMJSON work with Swift Package Manager?

Accepted Answer

Yes, PMJSON supports Swift Package Manager by adding the dependency to your Package.swift file, as detailed in the README. This allows easy integration into Swift projects across platforms.

Question 4

How to handle JSON streams with PMJSON?

Accepted Answer

Use JSON.decodeStream() to lazily parse multiple JSON values from a stream, or employ JSONParser directly for fine-grained control. This is ideal for scenarios like network streams or large datasets.

Question 5

Is PMJSON still maintained or should I use a fork?

Accepted Answer

The original repository is archived, so you must use the fork at PMSwift/PMJSON. Check the fork for updates and community activity, as maintenance is now community-driven with potential instability.

Question 6

What are common PMJSON error examples and fixes?

Accepted Answer

Errors often indicate type mismatches, e.g., 'expected string, found null'. Fix by adjusting your JSON structure or using optional accessors like getStringOrNil() to handle null values gracefully.
