Debugging and Logs
Troubleshoot your implementation of the iOS SDK and help OpenWeb improve the quality of the product.
Without impacting the performance of your app, the iOS SDK logging system can help you troubleshoot your implementation of the iOS SDK and help OpenWeb improve the quality of the product.
As a troubleshooting tool, the iOS log files offer the following benefits:
- Viewing logs in the console
- Saving logs locally in the application's Document directory
- Generating logs that can be submitted with a support ticket when issues are hard to reproduce
As an improvement tool, the iOS log files help OpenWeb to make the SDK more stable.
As for the performance of your app, the logging system has minimal impact:
- Log files are created in the
OpenWebSDKLoggerFileCreationQueue
queue with a.background
priority. - All other logging functions are performed in the
OpenWebSDKLoggerQueue
background queue with a.utility
priority.
No logs are sent to OpenWeb's backend servers.
Configure logging settings
When you configure the logger, OpenWeb disregards any pending logs. OpenWeb will not create files for these logs.
We strongly recommend configuring the logger after the initialization method. This ensures that files will be created for any pending logs.
By default, OpenWeb initializes the logger with the following settings:
logLevel: .verbose
logMethods: [.nsLog, .file(maxFilesNumber: 20)]
If you want to configure these default logging settings, you can call the following method.
SpotIm.configureLogger(logLevel: SPLogLevel, logMethods: [SPLogMethod])
SPLogLevel
Option | Description | Debug Symbol |
---|---|---|
none |
No logged items | -n |
error |
Logged items:
|
-e |
medium |
Logged items:
|
-m |
verbose |
Logged items:
|
-v |
SPLogMethod
While the following options can all be used together, we recommend using one of the following combinations:
[.nsLog, file(maxFilesNumber: Int)]
[.osLog, file(maxFilesNumber: Int)]
Option | Description |
---|---|
nsLog |
Apple NSLog |
osLog |
Preferred Apple OSLog framework |
file(maxFilesNumber: Int) |
Defines the maximum number of log files that will be created and stored in your application's Documents directorymaxFilesNumber : Maximum number log files that are stored locallyThe maxFilesNumber must be a number within the following range: 1-200. If the value passed is outside of this range, the default value of 20 will be used. |
NSLog
The following screenshots show the Xcode debugger console and device logs when using the NSLog framework.

Files
This option defines the maximum number of log files that will be created and stored in your application's Documents directory. After exceeding this number, the logger will remove the oldest log file when creating a new log file.
The logger will create a file in either of the following conditions:
- There are 100 items* to log.
* An item is each message logged by OpenWeb, such as a simple line or full information about a network request. The
SPLogLevel
affects the data within each item and if the item is logged. Based on testing,logLevel: .verbose
will not generate log files that exceed 1.5MB. - The application has moved to the background.
The following screenshots are examples from inside a simulator directory.

Disable logging
Log files can be an essential debugging tool. At minimum, we recommend enabling log files in your debug environment.
If you need to disable logging, you can call the following method.
SpotIm.configureLogger(logLevel: .none , logMethods: [])
