Swift capture
0 likes262 views
1. The document discusses Swift closures and capture semantics. It describes how closures capture variables by reference by default in Swift. 2. Examples are provided to demonstrate that captured variables are evaluated at closure execution time and that capture lists can be used to capture variables at closure creation instead. 3. The conclusion emphasizes that closures capture references to outer variables, values can be modified if variables are declared as 'var', and capture lists allow capturing variable values at closure creation.

What is while loop?AnuragSrivastava272
油
A while loop in C programming executes a target statement as long as a specified condition is true, making it useful for situations with an unknown number of iterations. The syntax is 'while(condition) { statement(s); }', and the loop stops executing when the condition becomes false. Key properties include the requirement of a condition expression, the possibility of having no loop body, and the option to omit braces for single statements.Flutter 2

Design Pattern in Swift Ch2 Strategy, DecoratorChihyang Li
油
This document discusses the Strategy and Decorator behavioral design patterns. The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. This allows algorithms to vary independently from the clients that use them. The Decorator pattern attaches additional responsibilities to an object dynamically at runtime without affecting other objects. Decorators provide a flexible alternative to subclassing for extending functionality. The document provides examples and comparisons of when each pattern would be applicable.Design Pattern Ch3 in Swift Composite
Design Pattern Ch3 in Swift CompositeChihyang Li
油

Navigating around the 1000 acres of UBC Vancouvers campus may look like a walk in a park, but when youre a student in a wheelchair trying to find a powered door to the class youre late for, it is not all that scenic. UBCs GIS team will share the journey from the original 2003 static map application to the current web application built using FME and the ArcGIS JavaScript API. There were two main goals with this new application: 1. Enable the UBC community to easily interact with and navigate the campus by walking, cycling and accessible means (which include mobility constraints such as steep slopes, stairs, and doors that are not powered). 2. Provide high quality geospatial data that is authoritative and updated using FME to reflect existing conditions on campus including road, sidewalk or building closures for construction. We will cover the unique challenges in creating a navigation application which offers features that Google Maps cannot at the scale of a University campus. Door to door navigation, avoiding stairs and steep slopes, navigating to accessible entrances and up to date construction barriers are some of the features we will discuss.Introduction to Agile Frameworks for Product Managers.pdf

In most modern programming languages, including Go, it's possible for a function to call itself recursively. It's such a mainstream technique that we've come to take it for granted.
But what if functions couldn't call themselves?
There's a branch of mathematics called Combinatorics which answers just these kinds of questions, and this presentation takes these ideas and phrases them in Go to teach a deeper view of computation through the medium of code.

This presentation is similar to another presentation I gave earlier in the year at the AWS Community Security Day, except that I had less time to present and incorporated some AI slides into the presentation. In this presentation I explain what batch jobs are, how to use them, and that AI Agents are essentially batch jobs. All the same security controls that apply to batch jobs also apply to AI agents. In addition, we have more concerns with AI agents because AI is based on a statistical model. That means that depending on where and how AI is used we lose some of the reliability that we would get from a traditional batch job. That needs to be taken into consideration when selecting how and when to use AI Agents as batch jobs and whether we should use AI to trigger an Agent. As I mention on one side - I don't want you to predict what my bank statement should look like. I want it to be right! By looking at various data breaches we can determine how those attacks worked and whether the system we are building is susceptible to a similar attack or not. Ad

- 110. Conclusion
- 111. Conclusion 1. Capture a reference to the outer variables that you use inside the closure
- 112. Conclusion 1. Capture a reference to the outer variables that you use inside the closure 2. Evaluated when the closure gets executed.
- 113. Conclusion 1. Capture a reference to the outer variables that you use inside the closure 2. Evaluated when the closure gets executed. 3. You can modify the variables value in the closure (if that variable is declared as var)
- 114. Conclusion 1. Capture a reference to the outer variables that you use inside the closure 2. Evaluated when the closure gets executed. 3. You can modify the variables value in the closure (if that variable is declared as var) 4. You can instead tell Swift to evaluate a variable at the point of the closure creation and store that value in a local constant, instead of capturing the variable itself. You do that using capture lists expressed inside brackets.
